Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A method for multiplexing control information, comprising: determining there is a conflict between resources assigned for a first uplink control channel for transmitting a service request and resources assigned for a second uplink control channel for transmitting a data acknowledgement; determining a downlink (DL) transmission mode is multiple input multiple output (MIMO) with rank two ( 2 ) transmission; and in response to the determinations, multiplexing the data acknowledgement and the service request by implementing a feedback restriction, the feedback restriction requiring that an acknowledgment transmission be used to acknowledge successful receipt of two downlink streams.
A method for handling simultaneous uplink control signals (service request and data acknowledgement) involves detecting when both signals are scheduled to use the same radio resources. If this conflict occurs AND the downlink transmission mode is MIMO with rank 2 (meaning two data streams are being sent), the method combines the acknowledgement and service request into a single multiplexed signal. This is achieved by enforcing a restriction where the acknowledgement signal *must* indicate successful reception of both downlink streams before the combined signal is transmitted, thereby resolving the conflict.
2. The method of claim 1 , further comprising modulating the multiplexed data acknowledgment and service request by quadrature phase-shift keying (QPSK).
The method of multiplexing control information where the acknowledgement and service request are combined into a single multiplexed signal when resources conflict and the downlink transmission mode is MIMO rank 2, and the acknowledgement signal acknowledges successful reception of two downlink streams, further specifies that this combined signal is modulated using QPSK (Quadrature Phase-Shift Keying). QPSK is a digital modulation technique that encodes two bits of data per symbol, allowing efficient transmission of the combined acknowledgement and service request information.
3. A method for multiplexing control information, comprising: determining there is a conflict between resources assigned for a first uplink control channel for transmitting a service request and resources assigned for a second uplink control channel for transmitting a data acknowledgement; receiving a scheduling restriction, the scheduling restriction requiring selection of single input multiple output (SIMO) when downlink transmission corresponds to a service request subframe; and multiplexing the data acknowledgement and the service request on the second uplink control channel using quadrature phase-shift (QPSK) modulation.
A method for handling simultaneous uplink control signals (service request and data acknowledgement) detects when both signals are scheduled to use the same radio resources. If a conflict occurs, and a scheduling restriction is received mandating the use of SIMO (Single Input Multiple Output) when downlink transmission corresponds to a service request subframe, then the method combines the acknowledgement and service request into a single multiplexed signal on the designated second uplink control channel. This combined signal is modulated using QPSK (Quadrature Phase-Shift Keying).
4. A method for multiplexing control information, comprising: determining there is a conflict between resources assigned for a first uplink control channel for transmitting a service request and resources assigned for a second uplink control channel for transmitting a data acknowledgement; receiving a scheduling restriction, the scheduling restriction requiring selection of multiple input multiple output (MIMO) rank one ( 1 ) when downlink transmission corresponds to a service request subframe; and multiplexing the data acknowledgement and the service request on the second uplink control channel using quadrature phase-shift (QPSK) modulation.
A method for handling simultaneous uplink control signals (service request and data acknowledgement) detects when both signals are scheduled to use the same radio resources. If a conflict occurs, and a scheduling restriction is received mandating the use of MIMO rank 1 when downlink transmission corresponds to a service request subframe, then the method combines the acknowledgement and service request into a single multiplexed signal on the designated second uplink control channel. This combined signal is modulated using QPSK (Quadrature Phase-Shift Keying).
5. An apparatus for transmitting multiplexed uplink control information, comprising: a computing platform for: determining there is a conflict between resources assigned for a first uplink control channel for transmitting a service request and resources assigned for a second uplink control channel for transmitting a data acknowledgement; and determining a downlink (DL) transmission mode is multiple input multiple output (MIMO) with rank two ( 2 ) transmission; a multiplexer for multiplexing the data acknowledgement and the service request by implementing a feedback restriction, the feedback restriction requiring that an acknowledgment transmission be used to acknowledge successful receipt of two downlink streams; and a transmitter for transmitting the acknowledgment transmission.
An apparatus for transmitting multiplexed uplink control information includes a computing platform to detect conflicts between resources assigned for transmitting a service request on a first uplink channel and a data acknowledgement on a second uplink channel. If a conflict is detected and the downlink transmission mode is MIMO with rank 2, a multiplexer combines the data acknowledgement and service request into a single signal. This combination enforces a restriction where the acknowledgement signal confirms successful reception of *both* downlink streams. A transmitter then sends this combined acknowledgement signal.
6. An apparatus for multiplexing uplink control information, comprising: a computing platform for determining there is a conflict between resources assigned for a first uplink control channel for transmitting a service request and resources assigned for a second uplink control channel for transmitting a data acknowledgement; a receiver for receiving a scheduling restriction, the scheduling restriction requiring selection of single input multiple output (SIMO) when downlink transmission corresponds to a service request subframe; and a transmitter for transmitting the data acknowledgement and service request by multiplexing the data acknowledgement and the service request on the second uplink control channel using quadrature phase-shift (QPSK) modulation.
An apparatus for multiplexing uplink control information includes a computing platform to detect conflicts between resources assigned for transmitting a service request on a first uplink channel and a data acknowledgement on a second uplink channel.

A transmitter sends the combined data acknowledgement and service request by multiplexing them onto the second uplink channel using QPSK (Quadrature Phase-Shift Keying) modulation.
8. A method for de-multiplexing control information, comprising: determining there is a conflict between resources assigned to a user equipment (UE) for a first uplink control channel for transmitting a service request and resources assigned to the UE for a second uplink control channel for transmitting a data acknowledgement; determining a downlink (DL) transmission mode is multiple input multiple output (MIMO) with rank two ( 2 ) transmission; and in response to the determinations, de-multiplexing the data acknowledgement multiplexed with the service request, wherein the data acknowledgment and the service request are multiplexed by implementing a UE feedback restriction, the feedback restriction requiring that a data acknowledgment be used to acknowledge successful receipt of two downlink streams.
A method for de-multiplexing combined control signals involves detecting conflicts where a user equipment's (UE) service request and data acknowledgement are scheduled to use the same radio resources. If a conflict exists AND the downlink transmission mode is MIMO with rank 2, the method separates the combined acknowledgement and service request signals. The original signals were multiplexed by applying a restriction on the UE's feedback: the acknowledgement signal *had* to confirm successful receipt of both downlink data streams before transmission.
9. The method of claim 8 , further comprising demodulating the data acknowledgment multiplexed with the service request, wherein the data acknowledgment multiplexed with the service request is modulated by quadrature phase-shift keying (QPSK).
The method of de-multiplexing control information where the acknowledgement and service request are separated because they were combined into a single multiplexed signal due to resource conflicts and MIMO rank 2 transmission, and the acknowledgement acknowledged successful reception of two downlink streams, further specifies that the combined signal is demodulated using QPSK (Quadrature Phase-Shift Keying). This recovers the separate acknowledgement and service request data encoded within the QPSK signal.
10. A method for de-multiplexing control information, comprising: determining there is a conflict between resources assigned to a user equipment (UE) for a first uplink control channel for transmitting a service request and resources assigned to the UE for a second uplink control channel for transmitting a data acknowledgement; transmitting a scheduling restriction to the UE, the scheduling restriction requiring selection of single input multiple output (SIMO) when downlink transmission corresponds to a service request subframe; and de-multiplexing the data acknowledgement and the service request by demodulating the second uplink control channel transmitted from the UE using quadrature phase-shift (QPSK) modulation.
